jQsimple-class is a small class declaration library for JavaScript. It allows you to easily declare classes and inherit from other classes, and lets you have constructors inline with your class declaration. It’s meant to let you quickly declare a class and easily extend others, then get completely out of your way.

Libfake437 is a cross-platform library for
rendering code page 437 'graphics' (think 'ANSI
art', ZZT, Dwarf Fortress, or Kingdom of Kroz).
The library is written in C and uses SDL for
drawing. The public interface is documented and
should be reasonably intuitive.

librsb is a library for sparse matrix computations featuring the Recursive Sparse Blocks (RSB) matrix format. This format allows cache-efficient and multithreaded (that is, shared memory parallel) operations on large sparse matrices. The most common operations necessary to iterative solvers are available (matrix-vector multiplication, triangular solution, rows/columns scaling, diagonal extraction/setting, blocks extraction, norm computation, formats conversion). The RSB format is especially well-suited for symmetric and transposed multiplication variants. On these variants, librsb has been found to be faster than Intel MKL's implementation for CSR. Most numerical kernels code is auto-generated, and the supported numerical types can be chosen by the user at buildtime. librsb implements the Sparse BLAS standard, as specified in the BLAS Forum documents.

soft66 is a library and related command line tools for controlling the Soft66AD series of SDR receivers from Kazunori Miura JA7TDO. This enables users of these software-defined radio receivers to tune and use them under Linux. There is also a patch to enable support for this in Linrad.
